While many are struggling in getting accepted in any campaign for which BCR and Duelbits are great campaigns, shan did wasted the opportunity that was given to him by these two great managers and as well as companies.
With so many members to handle, campaign managers might find it difficult if a member makes the switch before the tally.
AFAIK, they do some random checking for all of the participants. But then shan took advantage of it and he thought that no one will notice it but bbigtart seen it.
Thumbs up for Royse and Hhampuz for figuring out such a scam!
It was figured out by bbigtart -->
